Liver Enzyme Data
Description
Liver enzyme data collected from 218 patients with liver disease
(Plomteux, 1980). The laboratory profile consists of enzymatic
activity measured for four liver enzymes: aspartate
aminotransferase (AST), alanine aminotransferase (ALT),
glutamate dehydrogenase (GLDH) and ornithine carbamyltransferase
(OCT).
Usage
enzymes
Format
A data frame with 218 rows and the following 6 columns:
-
Patient: Patient ID -
Group: Four diagnostic groups were considered: acute viral hepatitis (1), persistent chronic hepatitis (2), aggressive chronic hepatitis (3) and post-necrotic cirrhosis (4). -
AST: Aspartate aminotransferase (in U/L) -
ALT: Alanine aminotransferase (in U/L) -
GLDH: Glutamate dehydrogenase (in U/L) -
OCT: Ornithine carbamyltransferase (in U/L)
